I think that if your theory is that the quality is in the sum total of all differences with other works, then it's not saying much. On the surface, texts are unique as snow flakes, so that's not a useful perspective. Some differences or features will surely play a larger role than others in determining quality. For the features that matter, commonalities might be more interesting than differences.

I think there might not be an effective difference between a particular interest acting like a filter, and the rest of the differences identifying a work. They appear to be different because the former is explicit and particular, but in the end our taste is conceivably described as a filter.

And I don't see why this couldn't pertain to literary or artistic value. You seem to suggest that shared features automatically imply genre works which are typically deemed of lower value. If artistic value is said to only reside in an ineffable difference of the whole work, then to me this is just a cop out to avoid having to define what that value actually is.
Yup, I go on lots of "Mile Runs" and it's actually quite difficult to do this with ITA Matrix as-is.

FreeBSD; I didn't trust any of the ZFS implementations for linux (I'm not sure there is one that works for your root filesystem yet?) and Solaris didn't find all of my hard drives.

If you're thinking of switching there really isn't much difference between FreeBSD and Linux (at least if you're talking about a traditional Linux like Slackware); most of the admin commands work like Linux did up until 5 years ago, and obviously the UI is just KDE or whatever you like.
> we can see from the trival case f(n)=3^n that O(3^n) is not a subset O(2^n) since 3^n > 2^n for all n as n approaches infinity, or there is no k such that is exists an n0, such that all n > n0 implies 3^n < k*2^n, therefore the two sets are not equal.

For what it's worth, this isn't really acceptable as a proof. The first half of your argument would go through equally well for 3n and 2n in place of 3^n and 2^n even though O(2n) = O(3n). The second half is simply a re-statement of what it means to say that 3^n is not in O(2^n) and doesn't actually prove it. The pertinent fact is that there is no constant k such that k >= (3/2)^n for all sufficiently large n because (3/2)^n goes to infinity as n goes to infinity. Compare this to the situation with 2n and 3n where (3n/2n) = 3/2 is a constant and hence bounded. A less trivial example would be something like n^2 + n versus n^2 where the ratio 1 + 1/n isn't constant but is nevertheless bounded for n >= 1.

I'd personally go as high as 6-8 in some scenarios. You can do a good bit with 512mb of memory of it's only doing a single task. Sometimes it's nice to keep things separated and compartmentalized.
That book is considered the 'Bible' of this area but I wouldn't recommend it to anyone who is looking to get started. It's like reading the dictionary.

As I understand it (h/t Joe Bowbeer), Doug Lea and others have been doing very cool work micro tuning data structures suitable for use on multicore systems. So it's possible. But definitely not trivial; certainly beyond my abilities.
Are you guys using FullContact for your profile information?
You still seem to be advancing your original point that hobby programming or side projects is an inferior pursuit relative to professional programming. McAfee was a shareware project, eBay was written by Pierre in a matter of days. I've seen many projects that were of much higher quality than many professional enterprise and startup projects.

Yes, the Joshua Slocum book, a classic well worth reading.

My book isn't in the same league, but it's developed a loyal following over the years -- it's online and free:

My all-time favorite sailing book quote, from a book titled "Never Again", about a sail in the terrifying "South 40s" near Antarctica: "After the mast blew off, the boat become much more stable." :)
Fascinating. Maybe they figured the Sedov was around back then so their claim would look a bit more legit...
Heh, no aerospace background for me, merely computer engineering. Maybe that's still close enough for the term to have crept around with that meaning. Now go forth and help spread this usage far and wide! ;)
I have to agree that this question set sits in between "useful CS topics" and "domain knowledge." Although a lot of people are building off of software libraries that use some heavy-duty CS knowledge, they need only be aware of the first-order implications - that there are different types of trees and sorts, that hashes, lists, and trees can expose similar interfaces while having different properties, that algorithm running time can be described with big-O notation. The fine differences are easy enough to research, and a responsible library author will document the expected runtime characteristics of their code.

On the other hand, something I'd expect to see on the final exam - and is already clearly absent based on the outline - is compiler design. If most of the world is doing web development and doing a lot of "slopping around of data between formats", parsing becomes important. Type systems become important. Code generation _may_ be important. And here, again, they don't have to be in-depth questions about the differences between LALR and packrat parsers, or describing the eight sides of the lambda cube. Simply demonstrating awareness of doing something other than mashing out a bad regex for every parsing problem would be an advance over the status quo.

What CIOs Need To Understand About Apple's Passbook Service
in the case where the attack is larger than your provider's pipe, they can't "just deal with it" - I mean, without blackholing the target IP address. If your transit ports are full, you are dropping packets. Undoubtedly, this is an advantage that larger providers (like amazon) have. On the other hand, most VPS customers would not want to pay $0.13 per gigabyte for DoS traffic.

>Also, null-routing for 24 hours regardless of if the attack only lasted 2 minutes, is a little silly.

It is a rather big deal for a hosting provider to lose connectivity for two minutes.
Perhaps both arguments are true, but not a problem. If reduction gives results, then it's useful; similarly for being fuzzy.
For larger hardware profiles the limit will definitely be higher. Current plans are for Standard Medium and Standard Large to be 6 and 8, respectively. So far no one seems to need more that that. Thanks for the feedback.

Box-shadow vs filter: drop-shadow
I'm a little disappointed that Wirth doesn't mention one of the key reasons that financial institutions use decimal floating point: that binary floating point can't produce exact representations of powers of 10, such as 0.1, and you may want to produce exact results for these situations, because fractions of a cent can really add up over time (see e.g. http://en.wikipedia.org/wiki/Salami_slicing).
>1/50 at age 43 is insignificant?

43 is quite far from 30.

Exactly.
The email that did get me to start using Flightfox was another one sent to you a few days later after you had signed up, looked around, but didn't end-up launching any contest.

In that email Flightfox said they noticed that I didn't launch any contest and gave me a coupon that covered 50% of any contest just to try it out.

So that's how I started using their service.

On the other hand I also learned there are other things to take into consideration when launching a contest. The most important one, knowing you have to buy the ticket as soon as possible. My contest was a tricky one (involving a toddler, timing international connections in the US, etc) so after 3 days there was only one decent result, and it was gone by the time I wanted to purchase it :(

So I guess that was the reason why the longest duration of the contests is of just 3 days. Which reminds me, I still need to go back there and do it all again.
How do you know all of these things? I would like to readup.
>Second mistake: don’t launch when somebody famous is in ill health.

Is this a joke? Steve Jobs was, more or less, in ill health for years and there are enough famous people to make this advice "don't launch ever."

Somehow I don't think I've ever heard of Minefold. Sounds like something I would have been interested when I was still playing. Two years ago, I dumped a few hundred hours into Minecraft though and got pretty burnt out.
I hope they fight this in court.
It's not TV, it's Silicon Valley in truth.

Discrimination by start-ups is enshrined in law. If you are a racist, you don't like old people, or you don't like Jews - no problem until you have 15 employees.

Fire your pregnant employees at will, crack down on sodomy - the start-up world is your discriminatory oyster: http://www.eeoc.gov/employers/coverage_private.cfm

California does have a law that tightens things up a bit, called FEHA. You only need 5 employees in California before you need to start treating people as you should: http://mccabeconsultants.com/forms/ADA%20Chart.pdf

I kid a bit in this post, but the limits on these laws are a two-edged sword. I think small companies can be crippled by pregnancies, and having the threat of a lawsuit about age discrimination can mess with your mind on hiring the right people. You can also imagine that a Hacedic markets should be run by Hacedic Jews. But there is certainly some amount of bad consequences from the limits on these laws, and a few too many white people running start-ups.
It's easier said than done.

Having listened to 5 decades of rocket launches, I would say that nominal means that it is working within mission parameters. There may be glitches, but it is going to work, i.e. the payload is going into orbit. The engine failure wasnt planned, but there was enough redundancy in the system for it to succeed.
The next 48 hours were spent fixing hundreds of bugs in all sorts of places we never expected things to go wrong.

Launching quickly # Launching prematurely.

I think that it takes this kind of suffering to fully appreciate the fine line between launching too early vs. too late. Sure, we're all in a rush with too much to do, but everyone should do themselves a huge favor and slow down long enough to come up with a good test plan, before, during, and after development.

I went through the same thing once and will never let it happen again. It was so bad, I actually considered becoming a cook instead. In the long run, it's just not worth it, to your customers, and mostly, to yourselves.
This makes Mark Cuban's article on High Frequency Trading (HFT) even more relevant than it was before (link: http://blogmaverick.com/2012/09/21/what-business-is-wall-str...). WHY is it not regulated or at the very least taxed, when it creates such outsized risk for the public and doesn't accomplish anything for the market besides increased volatility

Yes, middle class white people from affluent western societies like to do certain things that other people don't.

This. The kids mentioned in the article are all doing something with their gap year, and that's all well and good, but far too many of the kids I went to high school with just got part time jobs at Mickey D's and grumbled about how much they wanted to move out of their parents' houses, without doing anything toward that end.

What people don't seem to get about HFTs is that retail investors cannot and should not attempt to compete with them or trade actively at all - HFT or prop trading is a big no-no for the unsophisticated.

Historically buying into an index fund during a crisis is a perfectly reasonable way to achieve relatively easy alpha above the mutual fund/bond rates (~12% per year).

This type of investing (aka diversified value) is completely separate from HFT. As far as many retail investors should be concerned HFTs can duke it all out between themselves as much as they want - it really doesn't matter and is irrelevant to your long term investment decision.

Indeed HFTs provide the benefit that during times of crisis they provide plenty of buy side liquidity for you to get in at a lower spread and a lower spot price relatively easily.
They are experimenting with a number of different campaigns and are of course continually A/B testing the one I mention in the post but this is a nice snapshot for a certain point in time!

Hopefully we can cover more of their tests in the future as it's great stuff.

I'll make sure they see this comment too, in case they have any feedback.

Very Basic Startup Marketing
I'm guessing someone you know who has you in their phonebook downloaded the app and then it has one of those aggressive "send this download link to all my friends" type of thing and it's created a chain reaction where you have shared friends who then hit you when they sign up and so forth and so forth.
Another reason to limit trading to daily or weekly or montly. The trading arms race is focusing on speed when it should be focusing on predicting longer term outcomes. The easiest way to do so would be to limit all trades to once per day in an auction system. Then traders would pour their resources into building sophisticated systems that make long range predictions and so also identify new innovations/companies that should exist in the market. This is in literally almost everyone's best interest - investors, public corp's, governments, consumer - only a small group of high-speed traders would disagree. Why this hasn't occurred yet is mind-boggling.
This show had some potential but instead it's just another reality tv junk show--except this time it's about "us". Now I know what people in Jersey feel like.

IMO one of the larges inhibitors of entrepreneurship is a lack of confidence that is instilled by the education system. A thoughtful show about Silicon Valley could show how people from all different walks of life come here to build their dreams. It could inspire kids interested in technology to learn, it could show them that all you really need is an internet connection. Instead it shows that the typical tech entrepreneur is white(-ish), good-looking, outgoing and a party animal.

Congrats on launch! Not to spoil your party, there is another startup that is working in the similar space - www.luminate.com

What will be the primary use case of your product?
For those that have been down the startup road before - should this focus also be reflected in the same proportions in your budget? Ex. Should 50%+ of a startup's budget be spent on user acquisition/trying new things to gain users + increase conversion rates?
This looks like a co-brand card and so Google will not necessarily collect the interest revenue. All the risks and revenue are typically borne by the bank (there may be complex provisions so we will not know the exact deal structure for sure) and sometimes there will be profit sharing. Google will mainly save on the interchange (transaction fees) and may have a say on some of underwriting policies.
If it's Good I Don't Care Which License it Uses
I agree completely ... let the HFTs eek out a few pennies per trade (or even fractions of cents). But I also wanted to see how much bandwidth my 4G phone could really use. Sorry for the perturbations I might have caused and I promise I'm only doing what's good for man-kind. Now if I could just get my phone to make a decent call!
So, the video made it sound like someone was holding a large amount of stocks and very quickly sold all of them (like the flash crash). It didn't lead me to believe that they were placing orders and pulling them before they could be executed. Was this type of order discovered after the video recording, or am I misunderstanding what they said?

Also, in the video they say:

"What you're saying is the individual investor has no shot. Mary and Joe sitting out there have no quants on their staff"

My assumption was always that the average trader holds their shares over a longer period of time, and thus aren't really affected by these HFT algorithms. Is that assumption incorrect?

No need to have a hostile tone here. We have a guy from MS here. I'm sure he doesn't make policy decisions, like what ends up on the SEC report.

Ask HN: LXDE (Mint) or Xfce (XUbuntu)
1. I have a relatively old laptop (Pentium Dual-Core, T4200);
2. Its memory is OK(-ish): 4GB;
3. I never cared about eye candy and fluff, I always wanted the snappiest response available with zero visual effects;
4. I've narrowed down my choices to Xfce4 or LXDE (Ubuntu, respectively Mint);

Has anyone gone from one to the other? Which one has provided you with a better experience overall (meaning here not only the Desktop layer, but also the patches and general stability of the respective distribution)?

More seriously I wonder why random signals that appear to be noise but if noticed are actually quite pertinent to predicting trends have such a great effect on people.

Example follows:

Kennedy later claimed he knew the rampant stock speculation of the late 1920s would lead to a crash. It is said that he knew it was time to get out of the market when he received stock tips from a shoe-shine boy

Source: http://en.wikipedia.org/wiki/Joseph_P._Kennedy,_Sr.

For example if my mom came to me with an investment decision my response would be a big fat no - might even go out and look at it for a short. If my hairdresser recommended a stock to me - I'd feel immediately like selling. These are by definition low signal events that should be classified as pure noise - but they seem to be a rather useful thought model.

So party like it's 1997 - get in and get out.
What we solve - which we think is the biggest problem - is being able to ask what is inside an image.

You as a user, can grab any image, from any website - and ask what is inside it and others can help you. That's what we believe is the biggest problem.

The problem isn't arriving at an image and knowing - its arriving and not knowing. Luminate (and others) require the publishers to tag - however what if you arrive at some website (like the entire of instagram as one tiny example) and want to know what's in an image - where do you go ? Google - nope. That's just similar images they don't tell you any more. Luminate won't help you either.

So that's the difference - luminate and everyone else doesn't actually help you solve a problem as you surf the web.

Love to give you a preview if you're interested - we've done all this bootstrapped. We are only in beta so there will be bugs!
and therefore so am I...anyone else affected?

However, it's been growing steadily (almost at 60,000 players) and we've done some great work in the last few months which I can't wait to release :) I don't like taking this long between releases but we've had to re-think a lot of our internal systems (blog posts coming).
